I really like and respect Competitive Camera a lot. Ask for Eugene. I've never taken equipment that I didn't purchase there for repair and don't know if they even do repairs, but I bet they can point you in the right direction.
Note that they are super knowledgeable and honest. It can sometimes come across as abrasive, but it's never personal (basically, it is the anti-Best Buy).
Let us know how it goes.
